TRACTIONi-ENGNE.

Fatentedec. Q6, i916,

Application filed January 2,5, 1911. lSerial No. 604,539. i

' To @ZZ 'whom t may concern Y Be it known that l, ROBERT O. Hnnnnronson, .a citizen-of the` United States, residing atPortland-in the county of Multnomahs and State of'regon, have invented new and useful improvements in Traction-Engines,

vof which the following is a specification.

This invention relates'to traction engines, and conslsts 1n certain improvements in the of ,construction thereof as will be hereinafter vfully described and pointed out in the claims.v

In carrying out my invention l utilize the exhaust'from a iuid actuated motor, preferis ably internal combustion motor for cleaningand. lubricating the drive connection drivenv by the engine. Ordinarily in a traction, engine there is a gear secured to the traction wheels.l This gear is driven by a sa smaller gear or pinion driven by the engine. 'lhezgear on the traction wheels 1s of a size and so arranged that it is difficult to properly house this gear to exclude the dirt, and as these engines are used in many places 'where' they subjected to severe conditions in this respect, it is very desirable to have vsome arrangement for keeping the gears free from such dirt or dust, and at the same time for properly lubricating the at gears.

il: il

In my invention, l lead the exhaust from the motor to a point adjacent to the gears and direct the exhaust fluids against the gears preferably as they approach each other-so that at the moment of engagement,

or comin into mesh all the dirt has been 1 g s 7 blown ofl the gears through theaction of the exhaust, and at the same time, the Waste oil carried by the exhaust is deposited in suicient uantities on the Gears to ro erl 1 b iubricate them.

The invention is illustrated `1n the accompanying drawings as follows:

Figure l, shows a side elevation of a tracis tion engine, a part of the frame being broken away to better show construction. Fig.. 2, shows a plan view of a traction engine, a art being broken away to better show construction.

l marks the frame of the traction engine, 2 the traction wheel, 3 the steering wheel,

- 4 the engine mounted on the-frame. `The traction wheels are mounted on the axles 2a in any desired manner. The internal gears l 5 are arranged on the traction Wheels. The spur gears 6 mesh these internal gears 5. rlhe' gears 6 are fixed on the shafts 7 The shafts 7 are driven through lthe speed changing andldifferential mechanism 9 from the. engine shaft 10. l have shown only the' case outline of the differential and speed changing mechanism, but itl will be understood that any of the ordinary devices for this purpose may be used.

The motor shown is of the internal combustion type, and the exhaust fluids from the motor are gathered up in the manifold 11, and carried to the exhaust pipe 12. This leads to a cutout valve 13. Branch' pipes 14:

vleadl from the cutout valve terminating in the ends 415 which are adjacent to and directed against the gears at a point where they are approaching engagement. The cutout valve operates in the usual manner, and by its use the branch pipes may be cut out and the exhaust made direct. Normally,

however, the pipes 14 are in communication tor at one end and the other end of. which'` is open and directed against the engaging surfaces of the gears, substantially as de'- scribed.

2. In a traction engine, the driving mechanism of which comprises intermeshing gearl wheels and which is drivenby a iuid actuated motor, a connection from rthe exhaust of said motor arranged to direc/t the exhaust from the motor into the bite of said intermeshing gears, substantially as described..

3: ln a traction engine, circular racks upon the traction wheels thereof; pimons ieoegwe engaging suc'h racks, the racks and pinions being fully exposed, an internal combustion engine for driving the traction engine and a connection leading from the exhaust of said traction engine adapted to direct `the products of combustion into the bite of the rack and gear.

ln `testimony whereof I have hereunto Sei, my hand in the presence of two subscribing Witnesses. ROBERT OSCAR HENDRICKSOJ. Witnesses:
